The Tru Symphony 4D Plus is a luxury 4D SL-track massage chair with 46 airbags, a negative ion air generator, body scanning, zero gravity recline, heat therapy, and foot rollers at $7,999. The 46-airbag system is one of the most comprehensive air compression setups available at this price point — most chairs in the $6k–$8k range run 24–32 airbags. Combined with 4D roller technology that varies depth, speed, and rhythm mid-stroke, the Symphony 4D Plus delivers full-body coverage that most competitors at this tier can't match. Available in Brown and White/Gray.

Key Features

• 4D Roller System — adjusts depth, speed, and rhythm mid-stroke for a more human-like massage than fixed 3D systems; adapts to your body's contours rather than running a preset program
• SL-Track Coverage — continuous roller path from cervical vertebrae through glutes and upper hamstrings
• 46-Airbag Full-Body Compression — one of the most comprehensive air compression systems in this price tier; covers shoulders, arms, hips, calves, and feet simultaneously
• Negative Ion Air Generator — releases negatively charged ions to reduce airborne particulates and improve air quality during your session; typically found only in chairs above $10,000
• Body Scan Technology — maps your shoulder position and spinal curvature before each session, calibrating roller origin and pressure profile to your specific anatomy
• Zero Gravity Recline — elevates legs above heart level to reduce spinal compression and amplify massage effectiveness
• Heat Therapy — targeted warmth to loosen paraspinal muscles before and during the massage
• Foot Rollers — reflexology system stimulates key pressure points across the sole
• Premium Upholstery — luxury finish in Brown or White/Gray
• 1-Year Limited Warranty — covers defects in materials and workmanship under normal residential use

Specifications

What the 46-Airbag System Means in Practice

Most massage chairs use airbags to compress the arms and calves. The Symphony 4D Plus extends that to 46 airbags covering shoulders, arms, hips, calves, and feet — all working simultaneously. The effect is a full-body compression wave that improves circulation from the upper body down through the feet, rather than isolated compression at two or three points. For buyers who spend long hours sitting or standing, this is the feature that makes the biggest difference in how the chair feels after a full session.

Frequently Asked Questions

What does 4D mean in a massage chair?
3D rollers adjust depth (in/out) in addition to the standard up/down and side-to-side movement. 4D adds variable speed rhythm — the rollers speed up and slow down mid-stroke to mimic the natural cadence of a human hand rather than maintaining a fixed pace. The result is a more organic, less mechanical massage feel.

What is a negative ion air generator?
A negative ion generator releases negatively charged ions into the surrounding air. These ions bind to airborne particulates (dust, allergens, odor molecules) and cause them to fall out of the air rather than remaining suspended. The result is cleaner, fresher air in the immediate environment during your session — a feature that complements the relaxation state the massage is designed to produce.

Is White Glove delivery available?
Yes, in select locations at additional cost. Contact us before ordering to confirm availability and pricing. Free standard shipping to the lower 48 is always included.
